What's your recommendation/Best Practice?

I have been noticing some people have coated their chrome bumpers and trim, in a nice mate-black, and coated their fender flares, which over time, do fade (Constant battle). What are your "Best practices" for getting quality, lasting, durable results? I really like the bed liner on the finder flares. Would powder coating be a solid option for the bumpers.
I want something that is both aesthetically pleasing and functional. Thank you for your input.

 

I'm actually in the process of stripping my bumpers and grill from the paint that was on them and redoing them. I'll be using 2 or 3 coats of duplicolor adhesion promoter as the base, then 3 or 4 coats of duplicolor semi gloss to finish it off.

i think the biggest thing is make sure you prep well. ask anybody that knows something about painting, and they'll tell you 90% of the work should be in the prep.
